Japanese design firm Torafu Architects has invented a wedding ring that, like all good relationships, gets better with age! The ring is gold with a silver-plated exterior. As the months and years go by the silver wears off to expose the golden center.

Kind of reminds me of a jawbreaker candy. Except, in this case, by the time you get to the center you're not wondering why you bought it in the first place. Hopefully.
